Pioneer-Standard Electronics, Inc.
6065 Parkland Boulevard
Mayfield Heights, OH  44124

     We are acting as counsel for Pioneer-Standard Electronics, Inc., an Ohio
corporation (the "Company"), with respect to the 300,000 Common Shares, without
par value (the "Plan Shares"), to be offered and sold from time to time pursuant
to the Company's Retirement Plan and Retirement Plan II, as amended
(collectively, the "Plans"). As counsel for the Company, we have assisted in the
preparation of Post Effective Amendment No. 2 to a Registration Statement on
Form S-8, File No. 333-40750, (the "Registration Statement") to be filed by the
Company with the Securities and Exchange Commission under the Securities Act of
1933, as amended, with respect to the continued registration of the Plan Shares
to be offered and sold from time to time pursuant to the Plans.

     We have examined such documents, records and matters of law as we have
deemed necessary for purposes of this opinion, and based thereon we are of the
opinion that the Plan Shares have been duly authorized and, when issued and sold
from time to time in the manner contemplated by the Plan and the Registration
Statement, will be validly issued, fully paid and nonassessable.

     Our opinion is limited solely to the laws of the state of Ohio.

     This opinion is intended solely for your use in connection with the filing
of the Registration Statement with respect to the Plan Shares, and may not be
reproduced, filed publicly or relied upon by any other person for any purpose
without the express written consent of the undersigned.

     We hereby consent to the filing of this opinion as Exhibit 5.1 to the
Registration Statement.

                                         Respectfully submitted,

                                         /s/ Calfee, Halter & Griswold LLP
